### Technological Characteristics and Substantial Equivalence

The OcuLight SL/SLx Laser System is indicated for retinal photocoagulation, laser trabeculoplasty, TSCPC, and TSRPC. The expansion of the indications for use for the proposed OcuLight does not result in a change to the hardware or firmware for the currently marketed OcuLight.

{2}------------------------------------------------

The OcuLight GL Laser System is indicated for retinal photocoagulation and laser trabeculoplasty. The OcuLight GL is a semiconductor-based ophthalmic laser photocoagulator that delivers true continuous wave green laser (532 nm) light.

The OcuLight GL delivers similar power, use similar delivery devices, and have similar indications as the OcuLight SL/SLx.

The Keeler Instruments Microlase Diode Laser System is indicated for retinal photocoagulation. The Microlase diode laser system delivers a wavelength of 780 to 840 nm infrared laser light.

The Microlase delivers the same infrared wavelength, pulses of equivalent duration, treatment spots of equivalent size, and energy densities equivalent to the OcuLight SL/SLx.

The Nidek DC-3300 Laser Diode Photocoagulation is indicated for all retinal photocoagulation procedures. The DC-3300 and OcuLight SL/SLx use a variety of delivery systems, including slit lamps, indirect ophthalmoscopes, endoprobes, and transscleral probes.

The DC-3300 delivers a similar infrared wavelength, pulses of equivalent duration, treatment spots of equivalent size, and energy densities equivalent to the OcuLight SL/SLx.

#### Non-Clinical performance Data

None

#### Clinical performance Data

None

#### Conclusion

The OcuLight SL/SLx is substantially equivalent to predicate devices currently legally marketed for the indication of retinal photocoagulation, laser trabeculoplasty, transscleral cyclophotocoagulation, transscleral retinal photocoagulation, and other diode laser treatments.

Dear Mr. D'Angelo:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
